KPI Comm 2b: European technical leadership: quantum secure networks
KPI observatory / Quantum Communication
Physical distance and key rate of prepare-and-measure quantum key exchange, and the number of new protocols realised beyond prepare-and-measure QKD.
Official values: survey results of the Quantum Flagship Strategic Advisory Board, as published. Trajectory and live measure: calculations of this portal, not the assessment of the SAB.

Definition: Official KPI values and 2030 targets
Remarks and method
- ***: achieved with an entanglement-based protocol (BBM92).
- Scorecard note c: achieved with an entanglement-based protocol (BBM92).
- The 2030 target is under review (booklet notes, page 20).
Method as stated: Published result with an entanglement-based protocol (BBM92) (booklet reference Communication 2).
Trajectory (calculated by the portal)
Distance (km)
Not assessed
Not assessed: The indicator is a rank or a description, not a quantity.
The booklet rates each indicator on its own four-level scale (ahead of schedule, on schedule, needs progress, behind schedule); that assessment is not reproduced here.
Definition: Trajectory towards the 2030 target
Live measure of the portal
No automatic measure. Key exchange distances and new protocols come from experiments in the literature; the portal does not track them.
